Effects of Rifampicin on Rice ROS Metabolism with Salt Stress

WANG Zheng-chao,ZHOU Miao-ji,YE Xing-chan,HUANG Yan-ling,FANG Liang-jun*(Guangdong Ocean University,Zhanjiang,Guangdong 524088,China)  
Dealing rice cultivar 'R6' with Elicitor HI,rifampicin or their combination under salt stress,we investigated the effects of rifampicin on reactive oxygen species(ROS) metabolism in rice leaves.The results indicated that(1) the rice protect enzymes activity and O-·2 produce rate increased significantly under salt stress;(2)Rifampicin has a positive function on promoting rice salt tolerance to some extent and having an notable enhanced impact on improving rice salt tolerance after Elicitor HI treatment;(3)HI-RFP-S and RFP-S treatments improved the activity of SOD,POD and CAT,which impaired the hurt to cell membrane from O-·2.
